GAS-PRODUCER.

. Specification of Letters Patent.

Patented Aug. 4, 1914.

Application filed October 11, 1912: Serial No. 725,242.

a full, clear, and exact description of the in'ventiomsuch as will enable others skilled in the art to which it appcrtains to make and use the same.

I This invention relates to new and useful improvements in gas producers.

The principal object of the invention is to provide a gas producint apparatus which is mounted upon a solid foundation and whichincludes a mechanically operated totating poker which is also adapted to be raised and lowered so as to contact at all times wlth the coal.

Another object of the invention is to provide a gas producing apparatus in which the poker is kept-in a comparatively cool condition by means of running water which passes therctlu'ough.

A still further object of the invention is to provide a gas producer of the character described which is composed of a respectively few number of Parts, and is therefore Simple in construction'and cheap to manufacture.

\Vith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is'a sectional view through the apparatus taken transversely of the grate, Fig. 2 is a sectional View of the apparatus taken longitudinally of the rate, Fig. 3 'is an enlarged vertical sectionsil view through the poker shaft and su port, Fi 4 is a horizontal sectional View to on on to line 44 of Fig. 3, Fig. 5 is an enlarged horizontal sectional view r1ngs. 1 p Referring to the drawings my invention comprises a-base which cons sts of a number of spaced walls 5 5, the space between the Walls constituting a draft passage. Seated ing 9. Formed in the Walls 5 of the base below the shell 7 are pockets10-l0 in which water is placed and which form a bottom for said shel upon the walls is a cylindrical shell 7 said a .shell being provided with a fired brick li'n Supported upon the section 5 of the base i i is a grate which is designated as a whole by the reference letter A. This grate consists of a supportingelement with an inverted V-shaped cross section and comprises two inclinedsides, each side comprising a plu" rahty of plate sections 11-11. Disposed at the central portion of the apex of the grate is a vertical sleeve 20. Centrally sup orted between the base sections 5-5 and of the grate A is a hydraulic jack 33 which may be of any suitable construction, and includes a vertically movable head 34 disposed outwardly of the jack casing and having a bore 35 and a counter-bore 36'formed in its upper end. Rotatably mounted with the counter bore 36 is a vertically disposed hollow shaft 37, the bore 38 thereof communicating with the bore 35 of said head. At its upper end the shaft is journaled in the sleeve 20, and the shaft extends beyond the socket in an angular end 39. At the upper end of the bore 38 of the shaft is a laterally extending horizontal rotatable poker 41. A lateral passage 42 is formed in the angular end 39 of the shaft and this passage communicates with the bore 38 thereof and with a passage 43 which is formed in the poker' 41. This passage 43 extends longitudinally of the poker and is then returned as at 44 and thus continues rearwardly to the shafting as at 45. This end of the passage 43 is connected to the upper end of the pipe 46 which is disposed within'the bore 38 and has its lower end extending through the shaft 37 in a disirectly below the sleeve 20 r charge nozzle 47. This nozzle is disposed above a cup 48' which is carried by the shafting, and this cup is provided with a drain pipe 49. of the jack and this pipe communicates with the bore 38 of the shaft 37 and with a pipe 51 which leads from any suitable cool water supply.

From the foregoing it will be observed that water passes from the pipe 51, through the inlet pipe into the bore 38 of the shaft 37, thence upwardly through said bore through the lateral passage 42, passage 13 and is returned through the pipe 46. The water is then discharged from the nozzle 47 into the cup 43 and from said cup through the discharge pipe as. It will thus be observed that'the poker 41 is kept in a cooled condition by means of the runningwater regardless of the rotation of said poker or of the vertical passage thereof, due to the movement of the jack 33.

In order to rotate the shaft 87 and consequently""the poker 41 a worm Wheel 52 is connected to the shaft by a suitable feather, and

this wheel is supported upon the grate structure A by means of a suitable brace 53. The worm wheel 52 is driven from any suitable member (not shown).

From the foregoing it is observed that the poker may be rotated and at the same time gradually raised or lowered through the mass of burning fuel, a free flow of water through the poker and its supporting shaft being at all times effected while the apparatus is in operation, so that the poker remains properly cooled.

It is seen that a simple, eflicient, ,durable A pipe 50 is carried by the head 34 and easily operated device has thus been provided.

What 1s claimed is:

1. In a gas producing apparatus, a slidably ournaled shaft, a hydraulic Jack hav ing a swiveled connection with the shaft,

means for rotating the shaft, the shaft and the head of the jack being formed in alined bores, an inlet pipe communicating with the bore of the jack, a horizontally disposed poker carried by the upper end of the shaft, said poker being formed with a passage having one end communicating with the bore of the pipe and a pipe connnunicating with the other end of the passage and extending downwardly through the bore of the shaft.

2. In a gas producing apparatus, a hydraulic jack, a slidably journaled shaft swiveled to the head of the jack, said jack and shaft being formed with alining bores,

a basin carried by the head of the jack, an outlet for the basin, an inlet pipe communicating with the bore of the head, a horizon tally disposed poker carried by the upper end of the shaft and formed with a bent passage having one end communicating with thebore of the shaft, a pipe communicating with the other end of the passage and extending downwardly through the bore of the pipe and directed outwardly of the pipe to discharge in the basin and means for TOtkIM ing the shaft.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
